1、备份mysql数据库时候出错，导出数据：
[root@localhost ~]# mysqldump -uroot -p mysql >/root/bck.sql
Enter password:
mysqldump: Couldn't execute 'SET OPTION SQL_QUOTE_SHOW_CREATE=1': You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'OPTION SQL_QUOTE_SHOW_CREATE=1' at line 1 (1064)
2、查询是否mysqldump版本问题：
[root@localhost ~]# mysqldump --version
mysqldump Ver 10.13 Distrib 5.1.71, for redhat-linux-gnu (x86_64)
[root@localhost ~]# which mysqldump
/usr/bin/mysqldump
3、用5.6.23版本的mysqldump覆盖或者指定目录运行即可
[root@localhost mysql]# cp /opt/mysql/mysql-5.6.23-linux-glibc2.5-x86_64/bin/mysqldump /usr/bin/mysqldump
cp: overwrite `/usr/bin/mysqldump'? y
4、查看是否备份成功：
[root@localhost mysql]# mysqldump -uroot -h127.0.0.1 -p test > /root/1.sql
Enter password:
[root@localhost ~]# cat 1.sql
DROP TABLE IF EXISTS SC;
/!40101 SET @saved_cs_client = @@character_set_client /;
/!40101 SET character_set_client = utf8 /;
CREATE TABLE SC (Scid int(12) NOT NULL AUTO_INCREMENT,Cno int(10) NOT NULL,Sno int(10) NOT NULL,Grade tinyint(2) NOT NULL,
PRIMARY KEY (Scid)
